Potassium Formate powder easily soluble in water, non-toxic and non-corrosive, is a high-purity, dry crystalline organic salt used to formulate brine. Potassium formate is used to make high density and solids-free formate brine in the operations of water based drilling, completion, workover and fracturing, which require densities ranging from 8.4 to 13.1 lb/gal (1004 - 1573 kg/m3).

Formate brine make non-corrosive drilling and completion fluid formations that is stable in HTHP operations. Formate brine stabilizes shales, extend polymer stability and enhance borehole stability. Formate brine improves well productivity with excellent compatibility at reservoir conditions with reservoir fluids. Formate brine offers better hole cleaning and increases circulation rates by providing optimum hydraulic flow. Formate brine reduces potential formation damage resulting from clay swelling or clay dispersion or migration. These brines eliminate the potential of formation damage due to the precipitation of carbonate, bicarbonate or sulfate compounds associated with using calcium-base brines where formation waters contain high concentrations of bicarbonate and sulfate ions.
